Mr-Glass Construction in San Antonio Heights, CA | Spruce Contractors
We provide independent General Contractor – San Antonio Heights service for Mr-Glass throughout the area, including framed and semi-frameless shower enclosures, custom-cut glass panels, and walk-in shower conversions. The thing that changes our Mr-Glass work here more than anything else is the unincorporated county status: a shower or bath remodel that alters the enclosure footprint can pull in county permit review that a same-size job downhill in Upland would sail through. That means we template Mr-Glass glass only after framing and inspection sequence is settled, not before. Call (877) 265-5771 for a free estimate on any Mr-Glass product, repairs, or full shower remodels in the 91784 foothills.
Why San Antonio Heights Residents Choose Us for Mr-Glass Service
Nate Calloway grew up watching older homes get torn down and rebuilt in Hillsborough, and that early exposure to old framing and settled foundations shaped how our crew approaches Mr-Glass work here. We measure, template, and install Mr-Glass enclosures on hillside lots where walls aren’t square and grades shift with the seasons. That’s the product-specific repetition most contractors never get, because most of them aren’t running Mr-Glass enclosure jobs week after week.
Our team works with Mr-Glass framed sliding shower doors, semi-frameless enclosures, custom-cut mirror and glass panels, and pre-framed window and door glass units. When a roller fails or a bottom rail corrodes, we diagnose it in minutes because we’ve seen that exact failure on other homes in San Antonio Heights. We’re independent, not manufacturer-affiliated, which means we recommend what the house actually needs, not what a brand program tells us to push.

Common Mr-Glass Construction Problems We Solve in San Antonio Heights
- Dragging or jumping shower doors. Hard mineral water in the 91784 foothills gums up the lower track on Mr-Glass sliding doors. We replace worn OEM rollers and tracks before the door starts lifting out of the rail. Two or three years of mineral buildup is usually all it takes.
- Corroded bottom rails on framed enclosures. San Antonio Heights water is hard enough that the bottom rail finish pits and flakes from daily splash-through. We replace the rail and seal it against future pitting, rather than letting the corrosion eat into the glass channel.
- Leaking wall jambs on out-of-square openings. Older citrus-era estates and mid-century ranches in San Antonio Heights rarely have plumb walls. A stock Mr-Glass enclosure won’t sit tight against the wall jamb, and water leaks onto step-down tile floors. We re-block and shim the opening before templating glass.
- Anchor pull-out on semi-frameless panels. Hillside remodels with seasonal grade movement can flex wall framing enough to loosen glass panel anchors. We check backing and add blocking where the studs can’t hold the weight of a Mr-Glass semi-frameless panel.
- Mis-measured glass on remodel adds. When homeowners add a bathroom or convert a tub alcove, an incorrectly templated Mr-Glass panel is wasted money. We template after the framing and waterproofing are final, so the glass fits the corrected opening the first time.
Mr-Glass Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights sits in unincorporated county territory above the San Bernardino Valley, where steep private lanes and hillside grading shape every job. That’s the fact most contractors miss when they quote Mr-Glass work here. A shower remodel that changes the enclosure footprint, meaning the drain location or the curbed opening, can trigger county grading, fire, and road-access review that a flat-lot job in Upland would never face. Concrete trucks and glass delivery vehicles also fight narrow private drives, and many of these drives were cut decades before modern access standards. We’ve been through enough of these county reviews to know when a job stays a simple swap-out and when it needs an engineer’s stamp. On a mid-century ranch off a narrow private lane in the 91784 foothills, we converted a leaking tub alcove to a walk-in shower and hung a semi-frameless Mr-Glass enclosure. The original opening was nearly an inch out of plumb, so we re-blocked the studs and templated the glass to the corrected framing. The homeowner got a door that glides instead of drags. That’s the level of familiarity this hillside demands. See the full picture of our San Antonio Heights service area coverage.
Mr-Glass Models & Products We Service in San Antonio Heights
We service the full Mr-Glass lineup homeowners actually have in San Antonio Heights. That includes framed sliding shower doors, semi-frameless shower enclosures, custom-cut mirror and glass panels, and pre-framed window and door glass units. For repairs, we use OEM Mr-Glass rollers, hinges, and seals wherever they’re still manufactured, so the enclosure operates as designed. When OEM parts are discontinued, we source quality aftermarket hardware and tell you which one you’re getting before we install it. Most common rollers, tracks, and seals for Mr-Glass sliding doors are stocked locally, which keeps turnaround fast for San Antonio Heights calls. An intact glass panel with failing hardware is a repair. Cracked or mis-measured glass in a room we’re already remodeling is usually a replace, and we’ll tell you that plainly.

AfterMr-Glass Service Pricing in San Antonio Heights
Mr-Glass work in San Antonio Heights spans a few distinct service types, and the price reflects the scope. A hardware-only repair on a sliding shower door is a service call. A full walk-in shower conversion with a Mr-Glass enclosure is a construction project. Here are the ranges for the construction-side Mr-Glass work we handle most often:
| Service | Price Range |
|---|---|
| Walk-In Shower Installation | $4,500 – $12,000 |
| Frameless Glass Shower Enclosures (within Walk-In Shower range) | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Shower Replacement | $3,000 – $8,500 |
What drives cost most in San Antonio Heights is the condition of the framing and waterproofing behind the old enclosure, whether county permit review applies to the footprint change, and whether the opening needs re-blocking before glass can be templated. A free estimate includes exact measurements, a hardware-vs-replace recommendation, and a written line-item quote. Call (877) 265-5771 and we’ll walk you through it.

FAQs – Mr-Glass Construction in San Antonio Heights
Can a Mr-Glass shower enclosure be installed in an older San Antonio Heights home with out-of-square walls?
Yes, and this is one of the most common situations we see in San Antonio Heights. The fix is re-blocking and shimming the opening before templating the glass, so the enclosure sits tight against the wall jamb and doesn’t leak. A stock enclosure installed without correcting the opening will show gaps at the wall and leak onto the floor. Call (877) 265-5771 for an assessment of your specific bathroom.
Does replacing a shower or bath enclosure in 91784 need a county permit?
It depends on whether the project changes the enclosure footprint, meaning the drain location, the curbed opening, or the wall framing. Same-size swaps generally do not trigger county review, but an enclosure that changes the footprint can. We’ll tell you early in the estimate whether your job stays a simple swap-out or needs county review, and we handle the permit sequence if it does.
Why do Mr-Glass sliding shower doors start dragging in these foothill homes?
Hard mineral water is the main cause. San Antonio Heights water leaves calcium and mineral deposits on the lower track, and within a few years the rollers can’t travel smoothly. The door starts dragging, then jumping, then the rollers wear out. Replacing the OEM rollers and track usually restores smooth operation. Call (877) 265-5771 if your door is starting to drag, because waiting usually means more damage to the track.
Can your crew and glass delivery reach a steep private lane in San Antonio Heights?
In most cases, yes. We’ve navigated narrow private drives throughout the 91784 foothills and handled Wrightwood Mr-Glass service with similar access challenges, so we plan glass delivery around access constraints before the job starts. If a full-size glass truck can’t make the turn, we’ll arrange a transfer at the nearest accessible point. We’ll confirm access during the estimate so there are no surprises on install day.
Do you claim to be authorized by Mr-Glass?
No. We’re an independent Mr-Glass service provider, not manufacturer-authorized or affiliated. Our Mr-Glass expertise comes from years of measuring, templating, and installing these specific products on San Antonio Heights terrain, not from a brand program. That independence means we tell you plainly what needs repair and what needs replacing, and we source OEM parts where they’re available without a manufacturer’s incentives shaping the recommendation.
